Sound — 2
We played through this amp with a 1984 Kramer, an OLP MM3, and a couple of Ibanez 4-strings - one with passive, one with active pickups. The sound was decent, albeit remarkably quiet for a 100w. The deal-breaker, however, was the horrible, incessant 60Hz noise. It was causing the snare to resonate, and even made the guitar strings hum a bit. It was so incredibly maddening that we took it back to the store within a week. The sales associate told us that the noise is normal in an Ampeg combo, and that a 60Hz hum is actually desirable in an amp. I call "bull."
Overall Impression — 3
I suppose that $300USD for a 100w Ampeg sounds like a good deal, until you have to deal with that annoying, buzzing, humming sound. I can't say I'm ever going to look at a BA115 ever again, and I don't think I'll regret it. We returned the amp, and bought a Behringer Ultrabass BXR1800H Bass head to go with my spare 2x15 cabinet at home. No remorse, no regrets.
Reliability & Durability — 4
Well, it did survive a car ride home, about six hours of playing, and a car ride home. I can't say I'd ever want to play out with this steamer, though. I honestly don't know how anyone can find that sort of background noise desirable, and I have to seriously question the intelligence of the salesman Who talked the bassist into picking it up.
Features — 5
I'm just going to add to what other people have already posted here. The features on this amp are fairly standard, nothing spectacular, and basically what you can expect from a bass combo amp. I've got a few rather major complaints about this amp, as you'll discover when you read on.
